Evaluation of Resins for Stereolithographic 3D-Printed Surgical Guides: The Response of L929 Cells and Human Gingival Fibroblasts

Figure 6

Response of L929 and gingival fibroblasts activity to printed Clear and Dental SG resins that were not postcured in a direct cell culture model. L929 cells ((a), (c), and (e)) and gingival fibroblasts ((b), (d), and (f)) were seeded and cultured on printed Clear resin or Dental SG resin specimens which were not postcured. Then cells were subjected to MTT ((a), (b)) and resazurin-based toxicity assays ((c), (d)). Furthermore MTT staining was performed ((e), (f)). Data are given as mean standard deviation and are presented relative to the untreated control (W/O). Four independent experiments were performed. , resin versus W/O; the color of indicates the specific resin; , Clear versus Dental SG.
